Reconstruction of lateral defects of the tip and supratip less than 1.5 cm in diameter.

The authors describe the surgical technique as well as the indications and limitations of the East-West flap for repair of lateral defects of the tip/supratip of the nose less than 1.5 cm in diameter. This easy and reliable technique is based on the use of skin from the lower third of the nose to repair the defect.

Guidelines of the French Society of Otorhinolaryngology (SFORL), short version. Extension assessment and principles of resection in cutaneous head and neck tumors.

Cutaneous head and neck tumors mainly comprise malignant melanoma, squamous cell carcinoma, trichoblastic carcinoma, Merkel cell carcinoma, adnexal carcinoma, dermatofibrosarcoma protuberans, sclerodermiform basalioma and angiosarcoma. Adapted management requires an experienced team with good knowledge of the various parameters relating to health status, histology, location and extension: risk factors for aggression, extension assessment, resection margin requirements, indications for specific procedures, such as lateral temporal bone resection, orbital exenteration, resection of the calvarium and meningeal envelopes, neck dissection and muscle resection.

[Reconstruction of nasal cartilage defects using a tissue engineering technique based on combination of high-density polyethylene and hydrogel].

Aim Of The Study: Nasal reconstruction remains a challenge for any surgeon. The surgical indications for nasal reconstruction after oncologic resection, trauma or as part of cosmetic rhinoplasty, are steadily increasing. The current attitude for reconstruction is the use of autologous cartilage grafts of various origins (septal, ear or rib) trying to restore a physiological anatomy but their quantity is limited.

Saddle nose: classification and therapeutic management.

Introduction: The understanding and treatment of saddle nose have always been a surgical challenge. The authors propose a three-stage classification of this deformity as well as a treatment strategy adapted to each case.

Materials And Methods: A retrospective study was carried out on 25 patients with saddle nose.

Deep cervical granular cell tumor: an atypic location suggestive of neurogenic origin.

Introduction: Granular cell tumor (GCT), or Abrikossoff's tumor, is usually benign, with predominantly head-and-neck locations. Putative Schwann-cell origin is controversial. Treatment is surgical, due to risk of malignancy.

Thulium-YAG laser sialendoscopy for parotid and submandibular sialolithiasis.

Objective: To evaluate the efficacy and safety of thulium-YAG laser in sialendoscopic fragmentation of salivary lithiasis.

Design: Retrospective, interventional case series.

Material: Sixty-three patients treated by interventional sialendoscopy with thulium-Yag laser fragmentation between 2003 and 2010 at Edouard Herriot Hospital were included in the study.

Efficacy and safety of photodynamic therapy with temoporfin in curative treatment of recurrent carcinoma of the oral cavity and oropharynx.

Therapeutic options for recurrent carcinoma of the upper aérodigestive tract (UADT) are limited. The prognosis of these tumours remains poor with significant rate of recurrence and a lower median survival time. Photodynamic therapy (PDT) is a relatively new therapeutic alternative which combines the use of a photosensitising agent and light to induce a cytotoxic effect on the tissues.

Localized nasopharyngeal amyloidosis.

Objectives: To illustrate, via a case report, how a differential diagnosis of amyloidosis is to be suspected in case of a nasopharyngeal mass.

Case Report: A 59-year-old woman presented with bilateral nasal obstruction with associated episodic tubal dysfunction. Physical examination found a mass occupying the entire nasopharynx, initially suggestive of tumor.

[Importance of a molding nasolabial flap in the reconstruction of mobile nose defects, a review of 25 cases].

Introduction: Mobile nose reconstruction, because of its location, its anatomy and its functional role is a surgical challenge. We describe throughout this article the surgical technique and the importance of the nasolabial flap in a single-step procedure for repairing mobile nose defects.

Materials And Methods: We present 25 cases of mobile nose defects secondary to an oncologic etiology, affecting the supratip, the alar margin and the columella.

Maxillary sinus fungal infection by Acremonium.

Objective: To illustrate by this case report that Acremonium must now be considered as a differential diagnosis in cases of maxillary fungus balls.

Case Report: Seventy-seven-year-old woman consulted for persistent pain of the right maxillary sinus, with rhinorrhea and nocturnal coughing. Computed tomography (CT) of the sinuses showed a heterogeneous opacification of the right maxillary sinus with well-defined hyperdense foci suggesting aspergillosis.

Glioblastoma multiforme mimicking a frontal abscess after surgery for a large vestibular schwannoma.

Objectives: Routine vestibular schwannoma surgery can result in serious and potentially lethal infectious complications. A high degree of vigilance is necessary to diagnose these uncommon infections and in case of postoperative neurological symptoms, brain magnetic resonance imaging should be performed to eliminate a brain abscess. In some cases, the final diagnosis is not the expected one.

Twenty-four hours in the life of Zingel asper.

For the first time, radio-tracking observations were made over 24 h cycles during the growing season to quantify the habitat use and home range of Zingel asper, a critically endangered fish species, endemic to the Rhône River with a high risk of extinction (IUCN). New advances in radio telemetry with regard to the size of tags provided an opportunity to collect behavioural and habitat use information while remaining non-lethal. Zingel asper was characterized by small ranges of habitat use and, contrary to previous assumptions, the species was diurnal as illustrated by a smaller home range during the night than during daytime.

Biological influences on inter- and intraspecific isotopic variability among paired chondrostome fishes.

This study aimed at examining resource partitioning both at the inter- and intraspecific levels between paired chondrostome fishes: Chondrostoma nasus, the nase, C. toxostoma, the sofie, and their hybrid. The study was performed in the south of France and concerned a main river (the Durance River) and a tributary (the Buech River).
